plus gps works google maps has trails. If your riding side saddle hold on tight.
Yes, on both counts. The trail in starts out wide enough for cars, and quickly goes off into narrower trails. The picnic area by the river would be a great spot to stop and water (and wade), the banks are steep elsewhere.
Yes. Horses are allowed. Trails are marked as well. I'm not sure about a physical map, but there is a large map posted when you first enter.
